O B. 31,400 mm2
O C. 452.39 mm
O D. 314 mm2

Answer 1

D. 31,400mm^2

Explanation:

Answer 2

B. 31,400 mm2

Explanation:

We know that the bull's eye target has a diameter of 20 centimeters, which equals 200 milimeters.

So, we find the area

`A_(target)= \pi (100mm) ^(2) =(3.14)(10000) mm^(2) =31,400 mm^(2)`

Therefore, the right answer is B.
